dnstop is a libpcap application (ala tcpdump) that displays various
tables of DNS traffic on your network. Currently dnstop displays tables
of:
* Source IP addresses
* Destination IP addresses
* Query types
* Response codes
* Opcodes
* Top level domains
* Second level domains
* Third level domains
* etc...
dnstop supports both IPv4 and IPv6 addresses.
To help find especially undesirable DNS queries, dnstop provides a number
of filters. The filters tell dnstop to display only the following types of
queries:
* For unknown/invalid TLDs
* A queries where the query name is already an IP address
* PTR queries for RFC1918 address space
dnstop can either read packets from the live capture device, or from a
tcpdump savefile.
